We stayed for 5 nights in Lisa's place with our 2 kids. Thr location of the apartment was especially good and waking up with the market literally in front of our door or buying fruit from the salesman who passes in front was a memorable experience for us.
The shower, washing machine and air conditioning all worked fine. However, note that there is no air con on the bottom floors, only on the sleeping rooms upstairs. There is a fan downstairs which is passable but noisy.
As negative points we think the kitchen was extremely basic and there is no storage space whatsoever so we were living off our suitcases for 5 days.
Overall we were almost perfectly pleased with the apartment and would recommend it to anyone is visiting the main sights of Bangkok on foot.
